Chapter 30: Q3CQ (page 1110)
If atoms exist, why can’t we see them with visible light?
As the difference between an atom's size and the wavelength of visible light is too great, atoms cannot be seen with visible light.

The coating on the inside of fluorescent light tubes absorbs ultraviolet light and subsequently emits visible light. An inventor claims that he is able to do the reverse process. Is the inventor’s claim possible?
Integrated Concepts
What double-slit separation would produce a first-order maximum at 3.00o for 25.0 - keVx rays? The small answer indicates that the wave character of x rays is best determined by having them interact with very small objects such as atoms and molecules.
Which of the following spectroscopic notations are allowed (that is, which violate none of the rules regarding values of quantum numbers)?
(a) \[{\bf{1}}{{\bf{s}}^{\bf{1}}}\](b) \[{\bf{1}}{{\bf{d}}^{\bf{3}}}\] (c)\[{\bf{4}}{{\bf{s}}^{\bf{2}}}\](d)\[{\bf{3}}{{\bf{p}}^{\bf{7}}}\] (e)\[{\bf{6}}{{\bf{h}}^{{\bf{20}}}}\]
(a) An aspiring physicist wants to build a scale model of a hydrogen atom for her science fair project. If the atom is 1.00 m diameter, how big should she try to make the nucleus?
(b) How easy will this be to do?
Rutherford found the size of the nucleus to be about \({\bf{1}}{{\bf{0}}^{{\bf{ - 15}}}}\;{\bf{m}}\). This implied a huge density. What would this density be for gold?
